mouldings and panelled ingoes ; the door to the north recalls the sculptured door In the south gallery of S. Sophia, but, unfortunately, the carved work of the panels has been destroyed. Above the central door, on the interior, is a porphyry cornice carved with peacocks drinking at fountains (Plate LXXXVIL). Large portions of the beautiful marble revetment on the walls of the church happily remain intact, and nowhere else in Constantinople, except in S. Sophia, can this splendid method of colour decoration be studied to greater advantage. Slabs of various marbles have been split and placed on the walls so as to form patterns in the veining. The lower part is designed as a dado in Proconessian striped marble, with upright posts of dark red at the angles and at intervals on the longer stretches of wall, and rests on a moulded marble base. Above the dado are two bands, red and green, separated from the dado and from each other by white fillets. The upper part is filled in with large panels, especially fine slabs of brown, green, or purple having been selected to form the centre panels. The plainer slabs of the side panels are framed in red or green borders, and outlined with fillets of white marble either plain or carved with the € bead and reel/ The arches have radiating voussoirs, and the arch spandrils and the frieze under the cornice are inlaid with scroll and geometrical designs in black, white, and coloured marbles. The cornice is of grey marble with a * cyma recta' section, and is carved with an upright leaf*1
On the eastern walls of the north and south cross arms, and flanking the apse, eikon frames similar to those in the Diaconissa (p. 18 6) are inserted. The northern frame encloses a mosaic figure of Christ holding in His hands an open book, on which are the words, € Come unto Me all ye who labour and are heavy laden/2 In- the corresponding frame to the south is the figure of the Virgin, and, above it, an arch of overhanging acanthus leaves enclosed within a square frame with 'half figures of angels in the spandrils. The arch encloses a medallion bust, the head of which is defaced, but which represented the Saviour, as is proved by the indication
